Battery TLC in progress

Making sure both battery packs are in tip-top condition for this year’s record attempts. Each battery pack consists of 4 modules with 56 of A123 Systems’ 14 Ah high power cells in each module. That’s a lot of cells and a lot of battery management system boards that all have to work properly….

I had the great pleasure to be at The Project NZ TV show this evening (can be watched online for free, link below).

I was invited to talk about KillaJoule and the upcoming Big Boys Toys that is this weekend here in Auckland, NZ. However, the hosts were more interested in my 3D printed handbag with built-in LED light. It keeps amazing me how much people love that bag. I mean, why wouldn't I make my own bag to my exact desired specification when I made my own motorcycle..? ;-) If you know CAD (Computer Aided Design, which I teach at UoA) and 3D printing, you can make anything that can be manufactured from plastics.

6 hours of intense work, and the trailer now has a cover made from old The University of Auckland vinyl billboards. “University of Auckland Courses & Careers Day 2018” may have past, but this giant piece of heavy duty fabric is living on and protecting the KillaJoule from the weather on the way to Big Boys Toys! Just some final touches left for tomorrow such as hold downs and grommets, and the cover will be ready for highway speed.

Getting some really good use of that $250 industrial sewing machine from TradeMe (NZ’s equivalent to eBay or Craigslist).

--- Make helmet and racing suit for Barbie®! ----
Many of you really liked the Eva action figure, and so I have posted the design and written up all the instructions how to make the outfit.

If you have a doll lover at home, or just want your own racing action figure, you can now 3D print the helmet and sew the racing suit in 22 (!) simple steps. All needed files, patterns and instructions are found on my new website ScienceEnvy.com. It will fit Barbie and similar tall fashion dolls.

—- A love affair with a tool chest! —-
Move-in continues! We have really missed our _giant_ tool chest, which suitably enough was sponsored by the motorcycle parts supplier PartsGiant.com a few years ago.

Unloading a toolbox that literally weighs half a ton safely takes some seriously good teamwork and cleverness. I definitely have the perfect team mate in my lovely husband Bill Dube! 💚💚💚💚
